从xml文件加载控件

Question

我知道如何写入xml文件，但是我在做我需要做的事情时遇到了麻烦，并且找不到关于这类问题的足够信息。

下面是一个xml文件：

<?xml version="1.0" encoding="utf-8"?>
<controls>
    <Label Content="Double-click to edit." Location="258, 178" Size="101, 13" ForeColor="-1" />  
    <LinkLabel Content="Double-click to edit." Location="532, 133" Size="101, 13" LinkColor="-1" />  
    <LinkLabel Content="Double-click to edit." Location="424, 212" Size="101, 13" LinkColor="-1" /> 
    <Label Content="Double-click to edit." Location="282, 89" Size="101, 13" ForeColor="-1" />  
    <Label Content="Double-click to edit." Location="528, 178" Size="101, 13" ForeColor="-1" />  
    <LinkLabel Content="Double-click to edit." Location="528, 133" Size="101, 13" LinkColor="-1" />  
    <LinkLabel Content="Double-click to edit." Location="528, 149" Size="101, 13" LinkColor="-1" /> 
    <Label Content="Double-click to edit." Location="528, 164" Size="101, 13" ForeColor="-1" />
</controls>

在我的应用程序中打开这个文件后，我需要做的是：

foreach(control in XmlFile)
{   

  get Content
  get Location
  get Size
  get ForeColor/LinkColor
  // do something...
}

有人能帮我解决这个问题吗？如果能帮上忙我会很感激的。

谢谢

使用LINQ：(对于ForeColor/LinkColor检查为null)

XDocument loaded = XDocument.Load(@"C:\XMLFile1.xml");

            var q = from c in loaded.Descendants().Descendants()
                            select new
                            {
                                content = c.Attribute("Content"),
                                location = c.Attribute("Location"),
                                size = c.Attribute("Size"),
                                foreColor = c.Attribute("ForeColor"),
                                linkColor = c.Attribute("LinkColor")
                            };

            foreach (var controlItem in q)
                Console.WriteLine("Control content = {0}", controlItem.content);

如果您试图迭代XML中的所有控件并检索信息，则应使用XPath。

下面是一个示例：

XPathDocument Doc = new XPathDocument("yourfile.xml");
XPathNavigator navigator = Doc.CreateNavigator();
XPathNodeIterator iterator = navigator.Select("/controls/*");
while (iterator.MoveNext())
{
    System.Diagnostics.Debug.Print(iterator.Current.Content);
    System.Diagnostics.Debug.Print(iterator.Current.Location);
}
